GENERAL OPERATION
Daily Inspection
1.
Always set the parking brake, shut off power
unit engine, remove the ignition key, and ensure
all moving parts have come to a complete stop
before inspecting components, or attempting
any repair or adjustment.
Park machine on a level surface, with the engine
shut off and all fluids cold.
2. Perform a visual inspection of both the power
unit and the weather cab. Ensure the weather
cab is properly mounted to the power unit. Look
for loose or missing hardware, damaged com-
ponents, or signs of wear.
3. Check the power unit’s lights along with work
lights, hazard lights, and/or strobe light to
ensure lights are working properly.
4. Inspect window and door seals for cracks and
tears. Check glass for chips or damage.
5.
Inspect hydraulic hoses and fittings, fuel lines, and
heater lines to ensure tight, leak free connections.
6. Refer to the power unit operator’s manual.
Check the power unit’s engine oil, hydraulic oil,
cooling system, tire pressure, and fuel level. Add
fluid or service as required.
7. Repair or replace damaged or non-working
components.
8. Check the windshield wiper blade condition.
Clear any ice or snow from the wiper before
use. If blade is frozen to the windshield, care-
fully loosen or thaw the blade.
9. Clear any ice or snow from the windows and/or
defrost the windows before use. Do not operate
if visibility is restricted.
10. Test the power unit’s operator safety interlock
system*.
4-Point Seatbelt
Fasten the lower buckle of the 4-point seatbelt and
adjust the lap belt until snug but not tight. Tighten by
pulling bon the ends of the lap belt straps. Tighten
both sides evenly so the buckle remains centered
on the operator. Loosen by pulling up on the edge of
the seatbelt strap lock facing away from the buckle.
Upper buckle
location
Pull strap to
tighten
Lift up on tab
to release
Fasten the upper buckle of the 4-point seatbelt and
adjust the left and right shoulder belts. The shoulder
belts should be loose enough to allow the operator
to reach all dash controls, but should be snug at the
point that the operator can reach the dash controls.
Tighten the left and right shoulder belts by pulling on
the ends of the straps. Loosen the shoulder belts by
lifting up on the tab on the seatbelt strap lock
Adjust the upper buckle location so that the buckle
catches the operator in the middle of the chest when
the operator leans forward against the belt.
If the seatbelt cannot be tightened or loosened far
enough to properly fit the operator, the seatbelt
upper mount will need to be adjusted. Refer to seat-
belt upper mount adjustment in the service section
of this manual.
Strobe Light
The strobe light is mounted on a pivoting arm.
Rotate the strobe light up during operation. Rotate
the strobe light back and down for low clearance
areas, transport, or storage.
The strobe light arm is held in place by a spring. If
the strobe light or arm contacts an object, the spring
releases the pivot arm to rotate either forward or
backward away from the object. If this occurs, stop
operation and return the strobe light to the operating
position when clearance allows.
* Refer to power unit operator’s manual for operation of
power unit controls.
